Legal Definition of International Court of Justice

Definition of International Court of Justice

Further reading

The International Court of Justice (French: Cour internationale de Justice; commonly referred to as the World Court or ICJ) is the primary judicial organ of the United Nations. It is based in the Peace Palace in The Hague, Netherlands. Its main functions are to settle legal disputes submitted to it by states and to provide advisory opinions on legal questions submitted to it by duly authorized international organs, agencies, and the UN General Assembly.

The Court's workload covers a wide range of judicial activity. To date, the ICJ has dealt with relatively few cases. However, since the 1980s there has been a clear increase in willingness to use the Court, especially among developing countries. After the court ruled that the U.S.'s covert war against Nicaragua was in violation of international law (Nicaragua v. United States), the United States withdrew from compulsory jurisdiction in 1986. The United States accepts the court's jurisdiction only on a case-by-case basis. Chapter XIV of the United Nations Charter authorizes the UN Security Council to enforce World Court rulings. However, such enforcement is subject to the veto power of the five permanent members of the Council. Presently there are twelve cases on the World Court's docket.

Composition

The ICJ is composed of fifteen judges elected to nine year terms by the UN General Assembly and the UN Security Council from a list of persons nominated by the national groups in the Permanent Court of Arbitration. The election process is set out in Articles 4-19 of the ICJ statute. Judges serve for one year terms and may be re-elected for up to two further terms. Elections take place every three years, with one-third of the judges retiring (and possibly standing for re-election) each time, in order to ensure continuity within the court.

Should a judge die in office, the practice has generally been to elect a judge of the same nationality to complete the term. No two may be nationals of the same country. According to Article 9, the membership of the Court is supposed to represent the "main forms of civilization and of the principal legal systems of the world". Essentially, this has meant common law, civil law and socialist law (now post-communist law). Since the 1990s four of the five permanent members of the Security Council (France, Russia, the United Kingdom, and the United States) have always had a judge on the Court. The exception was China (the Republic of China until 1971, the People's Republic of China from 1971 onwards), which did not have a judge on the Court from 1967-1985, because it did not put forward a candidate. The rule on a geopolitical composition of the bench exists despite the fact that there is no provision for it in the Statute of the ICJ.

Judges may deliver joint judgments or give their own separate opinions. Decisions and Advisory Opinions are by majority and, in the event of an equal division, the President's vote becomes decisive. Judges may also deliver separate dissenting opinions.

Jurisdiction

As stated in Article 93 of the UN Charter, all 193 UN members are automatically parties to the Court's statute. Non-UN members may also become parties to the Court's statute under the Article 93(2) procedure. For example, before becoming a UN member state, Switzerland used this procedure in 1948 to become a party. And Nauru became a party in 1988. Once a state is a party to the Court's statute, it is entitled to participate in cases before the Court. However, being a party to the statute does not automatically give the Court jurisdiction over disputes involving those parties. The issue of jurisdiction is considered in the two types of ICJ cases: contentious issues and advisory opinions.

Law applied

When deciding cases, the Court applies international law as summarised in Article 38 of the ICJ Statute provides that in arriving at its decisions the Court shall apply international conventions, international custom, and the "general principles of law recognized by civilized nations". It may also refer to academic writing ("the teachings of the most highly qualified publicists of the various nations") and previous judicial decisions to help interpret the law, although the Court is not formally bound by its previous decisions under the doctrine of stare decisis. Article 59 makes clear that the common law notion of precedent or stare decisis does not apply to the decisions of the ICJ. The Court's decision binds only the parties to that particular controversy. Under 38(1)(d), however, the Court may consider its own previous decisions. In reality, the ICJ rarely departs from its own previous decisions and treats them as precedent in a way similar to superior courts in common law systems. Additionally, international lawyers commonly operate as though ICJ judgments had precedential value.

If the parties agree, they may also grant the Court the liberty to decide ex aequo et bono ("in justice and fairness"), granting the ICJ the freedom to make an equitable decision based on what is fair under the circumstances. This provision has not been used in the Court's history. So far the International Court of Justice has dealt with about 130 cases.
